Measurement invariance of the LGBT People of Color Microaggressions Scale among LGBTQ+ youth

The LGBT People of Color Microaggressions Scale (LGBT-PCMS) is a widely used measure of intersectional microaggression experiences among sexual and gender minority people of color. Although it is widely used-and increasingly used in adolescent and young adult samples-it is unknown whether the LGBT-PCMS demonstrates similar measurement properties across subgroups of sexual and gender minority youth of color (SGMYOC). Among 4142 SGMYOC (ages 13-17) we found evidence for either partial or full scalar invariance (item loadings and intercepts were generally equal) across sexual orientation, race-ethnicity, and gender identity groups for all three subscales. Specific patterns of invariance and noninvariance across groups, as well as implications for the use of the LGBT-PCMS and its subscales among SGMYOC are discussed.

Sexual Identity Disclosure and Alcohol Experiences Among LGBTQ+ Adolescents

Sexual and gender minority youth (SGMY) report greater alcohol use in comparison to their heterosexual counterparts. Prior research has found that elevated alcohol use among SGMY can be explained by minority stress experiences. Sexual identity outness may be another factor that drives alcohol use among SGMY, given that outness is associated with alcohol use among older sexual and gender minority samples. We examined how patterns of sexual identity outness were associated with lifetime alcohol use, past-30-day alcohol use, and past-30-day heavy episodic drinking. Data were drawn from the LGBTQ National Teen Survey (N = 8884). Participants were SGMY aged 13 to 17 (mean age = 15.59) years living in the US. Latent class analysis was used to identify sexual identity outness patterns. Multinomial regressions were used to examine the probability of class membership by alcohol use. Six outness classes were identified: out to all but teachers (n = 1033), out to siblings and peers (n = 1808), out to siblings and LGBTQ+ peers (n = 1707), out to LGBTQ+ peers (n = 1376), mostly not out (n = 1653), and very much not out (n = 1307). SGMY in classes characterized by greater outness to peers, friends, and family had greater odds of lifetime alcohol use compared with SGMY in classes characterized by lower outness. These findings suggest that SGMY with greater sexual identity outness may be a target for alcohol use prevention programming. Differences in sexual identity outness may be explained by minority stress factors.

Stigma and lesbian, gay, bisexual, transgender, and queer (and additional identities) (LGBTQ+) parent socialization self-efficacy: Mediating roles of identity and community

In the United States, cultural forces have led to the stigmatization of lesbian, gay, bisexual, transgender, and queer (and additional identities) (LGBTQ+) parenthood. However, pushing back against this stigmatization, developing a positive LGBTQ+ identity, and investing in one's LGBTQ+ community may inform empowering narratives of future parenthood and related constructs, such as LGBTQ+ parent socialization. Perceived self-efficacy related to preparation for bias (i.e., discussions of discrimination, prejudice, or bias-based bullying) socialization is likely associated with an individual's own perceptions or experiences of stigmatization given the conceptual overlap of bias and stigma. However, other constructs related to stigmatization and socialization self-efficacy, such as positive LGBTQ+ identity or community connectedness, have yet to be simultaneously considered (to our knowledge). Further, previous research has rarely included different assessments of stigma (i.e., perceived and enacted) and/or dimensions of positive LGBTQ+ identity (i.e., authenticity and self-awareness). Thus, this study aimed to rectify these gaps and provide a greater understanding of sexual stigma and LGBTQ+ parent socialization self-efficacy. Using data from a survey-based, online, cross-sectional study of LGBTQ+ childfree adults (N = 433; Mage = 29.85 years old) in the United States, we found that experiences of enacted or perceived sexual stigma were differentially associated with LGBTQ+ parent socialization preparation for bias self-efficacy. Further, positive LGBTQ+ identity authenticity and self-awareness, as well as LGBTQ+ community connectedness played distinct roles as mediators of the relationships between sexual stigma and LGBTQ+ parent socialization self-efficacy. These findings have implications for how we might understand the role of stigma, identity, community, and socialization among future LGBTQ+ parents.

Microaggression and discrimination experiences among diverse youth with LGBTQ+ parents in the United States

Family-based microaggressions and discrimination experienced by youth with LGBTQ+ parents are important to understand from their perspectives. Using mixed methods, we examined such experiences among 12- to 25-year-old youth (N = 51) with at least one LGBTQ+ parent in the United States. Youth were diverse in race/ethnicity, family structure, gender and sexual identities, socioeconomic status, and geographic region. Using interviews, we explored LGBTQ+ family-based microaggressions (reported through scale items with feedback) and discrimination (assessed via thematic analysis). Microaggressions and discrimination based on having LGBTQ+ parents were common, yet there were distinctions in direct and indirect stigma across the quantitative items and qualitative themes. These results underscore the value of mixed methods research with youth and implications for future research, practice, and policy.

HIV Information Avoidance, HIV Stigma, and Medical Mistrust among Black Sexual Minority Men in the Southern United States: Associations with HIV Testing

Uptake of HIV testing is a critical step in the HIV prevention and treatment care cascade. Barriers to HIV testing, however, remain and innovative research in this area is warranted to improve uptake of testing. As such, we investigated the role of HIV information avoidance - a novel construct potentially related to HIV testing. We analyzed this construct in relation to other factors known to impact HIV testing, namely HIV stigma and medical mistrust. Multiple linear regression analyses indicated that HIV information avoidance was negatively associated with HIV testing, while medical mistrust was positively associated with HIV testing. HIV testing stigma was not associated with HIV testing. This work contributes to the developing literature on HIV information avoidance and its relationships with HIV stigma and HIV testing uptake. Further, these findings can inform HIV testing interventions which often do not focus on HIV information avoidance. Future research on the mechanisms of information avoidance that are amenable to intervention, and the temporal ordering of the relationship between information avoidance and HIV testing is warranted.

Bullying Involvement at the Intersection of Gender Identity/Modality, Sexual Identity, Race, Ethnicity, and Disability: Prevalence Disparities and the Role of School-Related Developmental Assets

Purpose: This study examines adolescents' self-reported school-based developmental assets and four intersecting social positions as they relate to prevalence of bullying involvement. Methods: Participants were 80,456 ninth and 11th grade students who participated in the 2019 Minnesota Student Survey (30.2% youth of color; 11% lesbian/gay/bisexual/pansexual/queer/questioning; 2.9% transgender/gender diverse [TGD] or gender questioning). Exhaustive Chi-square Automatic Interaction Detection analysis was used to identify school-based developmental assets (i.e., school safety, school adult support) and intersecting social positions (i.e., sexual identity; gender identity/modality; racial/ethnic identity; physical disabilities/chronic illness; and/or mental health/behavioral/emotional problems) associated with the highest prevalence of involvement as physical and relational bullies, victims, and bully-victims. Results: Adolescents with 2+ marginalized social positions who often lacked school-based developmental assets were part of nearly all the highest prevalence bullying involvement groups. TGD and gender questioning adolescents, Native American youth, and youth living with both physical disabilities/chronic illness and mental health/emotional/behavioral problems-most of whom had additional marginalized social positions and lacked school-based assets-were particularly overrepresented in high prevalence groups. For example, 31.1% of TGD or gender questioning youth of color living with both types of disabilities/health problems who did not feel strongly that school was safe reported involvement as physical bully-victims-nearly six times the sample average rate. Conclusion: Adolescents with multiple marginalized social positions and those lacking certain school-based assets-often overlapping categories-were involved in bullying at higher-than-average rates. Findings underscore the need for schools to address intersecting experiences of stigma and structural oppression that may perpetuate bullying involvement disparities.

"This Is To Help Me Move Forward": The Role of PrEp in Harnessing Sex Positivity and Empowerment Among Black Sexual Minority Men in the Southern United States

In the United States (U.S.), Black sexual minority men (BSMM) are disproportionately burdened by HIV. Prevention advances, such as HIV pre-exposure prophylaxis (PrEP), play a key role in reducing HIV transmission and improving our understanding of sexual expression and health. Despite these advances, little is known regarding the potential link between PrEP use and positive sexuality, including the benefits that BSMM see in accessing PrEP. We conducted a thematic analysis of 32 interviews with BSMM in the Southern U.S. regarding their PrEP beliefs. We developed five themes: (1) Sexual freedom, (2) Agency and empowerment, (3) Making PrEP normative, (4) Behavioral health practices, and (5) Committed relationship tensions. Our findings suggest that BSMM are increasingly concerned about freedom of choice and invested in sexual empowerment as related to their PrEP use. Further, unanticipated benefits, community support, and relationship tensions are salient factors in considerations of PrEP use among BSMM. These findings have implications for how we might understand a broader movement toward sexual empowerment and positivity, and the pivotal role that PrEP serves in this movement.

Black Sexual Minority Men's Stigma-Based Experiences Surrounding Pre-exposure Prophylaxis in the Southern United States

Purpose: Intersecting experiences of stigma related to pre-exposure prophylaxis (PrEP) influence PrEP uptake among Black sexual minority men (BSMM) living in the southern United States; however, it is unclear what stigmatized identities and behaviors are impacted when accessing human immunodeficiency virus prevention options. To inform identity-specific PrEP interventions, this study examined stigma in BSMM's lives relating to intersecting experiences of PrEP stigma. Methods: We conducted 32 virtual, semistructured qualitative interviews with BSMM residing in the southeastern United States between February and April 2019. Results: We identified three themes (anticipated stigma, experiences of prejudice and stereotyping, and negative attitudes) and one subtheme within negative attitudes (othering social/sexual groups). Across all themes, PrEP stigma was often manifested through stigma against BSMM's sexual orientation or sexual behavior. BSMM in othering social/sexual groups displayed instances of cognitive dissonance by regularly expressing negative attitudes about and explicitly distancing themselves from social/sexual groups based on sexual orientation and sexual behavior. BSMM's race and gender were rarely mentioned as being stigmatized. Conclusions: Interventions focused on PrEP use could benefit from expanding their definition of PrEP stigma to include a stronger emphasis on intersecting identities and work to reduce cognitive dissonance in BSMM in the form of internalized homophobia.

Complex Outness Patterns Among Sexual Minority Youth: A Latent Class Analysis

Prior scholarship has documented health-relevant consequences of sexual minority youth (SMY) sexual identity disclosure (i.e., "outness"), yet most of the extant work focuses on one social context at a time and/or measures outness as dichotomous: out or not out. However, SMY are out in some contexts (e.g., family, friends) and not in others, and to varying degrees (e.g., to some friends, but not to all). Using a national sample of 8884 SMY ages 13-17 (45% cisgender female, 67% White, 38% gay/lesbian and 34% bisexual, and 36% from the U.S. South), this study used latent class analysis to identify complex patterns of outness among SMY, as well differences in class membership by demographics, depression, family rejection, and bullying. The results indicated six distinct classes: out to all but teachers (n = 1033), out to siblings and peers (n = 1808), out to siblings and LGBTQ peers (n = 1707), out to LGBTQ peers (n = 1376), mostly not out (n = 1653), and very much not out (n = 1307). The findings reveal significant differences in class membership by age, sexual identity, gender identity, race and ethnicity, geography, and well-being outcomes. Moreover, these findings underscore the complex role of outness across social contexts in shaping health and well-being.

Contextualizing the Well-being of Asexual Youth: Evidence of Differences in Family, Health, and School Outcomes

Despite increasing efforts to better understand sexual and gender minority youth (SGMY), asexual youth remain understudied. This study examines differences in health, family support, and school safety among asexual youth (n = 938) from a national study of SGMY (N = 17,112) ages 13-17. Compared to non-asexual youth, asexual youth were more likely to identify as transgender and report a disability, and less likely to identify as Black or Hispanic/Latino. Transgender (versus cisgender) asexual youth fared worse on most study outcomes. Cisgender asexual (versus cisgender non-asexual) youth fared worse on all study outcomes. Transgender asexual (versus transgender non-asexual) youth reported lower sexuality-related family support. These findings underscore the role of gender identity in understanding the experiences of asexual youth.

Development of the Conceptual Future Parent Grief (CFPG) Scale for LGBTQ+ people

Parenthood is highly valued around the world. Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) people, however, have faced a history of discrimination and challenges related to becoming parents (e.g., legal and/or practical barriers to adoption or biological parenthood). As such, LGBTQ+ youth may believe that certain pathways to parenthood (or parenthood itself) are unavailable to them. These feelings could prompt experiences of ambiguous loss related to a future idealized self. No quantitative research, however, has been conducted to capture these possible experiences; scale development is an important step to attempt to quantify them. Here, we report results from two studies using exploratory and confirmatory factor analysis to investigate the factor structure of a new scale reflecting conceptual future parent grief (CFPG) among LGBTQ+ individuals. Participants also responded to several measures to explore validity with the CFPG scale. Following model respecification, a 9-item one-factor solution resulted, reflecting ambiguous loss, complex grief, and sexual stigma-all of which could contribute to difficulties in reconciling one's LGBTQ+ and future parenthood identities. Significant associations with greater authenticity of LGBTQ+ identity, depressive symptoms, and sexual stigma provided evidence of convergent and divergent validity with the CFPG scale. Thus, ambiguous loss among LGBTQ+ people may connect to aspects of identity, mental health, and parenthood goals. Developing this scale represents a first step toward an assessment for LGBTQ+ individuals regarding future parenthood. Understanding more about CFPG among LGBTQ+ individuals could inform prevention efforts to reduce negative mental health symptoms and enhance positive LGBTQ+ identity development.

Crack cocaine smoke on pregnant rats: Maternal evaluation and teratogenic effect

This study aimed to evaluate maternal toxicity, teratogenic, and placental oxidative effects resulting from the exposure of rats to crack cocaine smoke during pregnancy. Pregnant rats were exposed either to the smoke of crack and ashes (Crack) or to the smoke of ashes alone, nonexposed or pair-fed with the Crack group. Crack group was exposed to the smoke resulting from the burning of 250 mg of crack for 10 min, twice a day, from 7 days prior to mating until cesarian on gestational day 20. Placental oxidative stress and classical parameters of maternal and fetal evaluation were studied, in addition to the morphometric analysis of the fetal metamers. Even in the absence of changes in body weight gain and feed intake, crack altered the reproductive performance of dams. Exposure to the drug promoted late closure of the fetal fontanel. Furthermore, the morphometric study of the brain mass (BM)/skull cap ratio revealed a decrease in the BM of the fetuses exposed to the drug. Exposure to crack has an oxidative potential in fetal development, since exposure to the drug promoted placental lipid peroxidation. Our study showed that daily exposure to crack, even in lower frequency than that performed by users, has a teratogenic potential.

In situ rat brain and liver spontaneous chemiluminescence after acute ethanol intake

The influence of acute ethanol administration on the oxidative stress status of rat brain and liver was assessed by in situ spontaneous organ chemiluminescence (CL). Brain and liver CL was significantly increased after acute ethanol administration to fed rats, a response that is time-dependent and evidenced at doses higher than 1 g/kg. Ethanol-induced CL development is faster in liver compared with brain probably due to the greater ethanol metabolic capacity of the liver, whereas the net enhancement in brain light emission at 3 h after ethanol treatment is higher than that of the liver, which could reflect the greater susceptibility of brain to oxidative stress. The effect of ethanol on brain and liver CL seems to be mediated by acetaldehyde, due to its abolishment by the alcohol dehydrogenase inhibitor 4-methylpyrazole and exacerbation by the aldehyde dehydrogenase inhibitor disulfiram. In brain, these findings were observed in the absence of changes in the activity of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and glucose-6-phosphate dehydrogenase. However, the content of brain glutathione was significantly decreased by 31%, by ethanol, thus establishing an enhanced oxidative stress in this tissue.

Influence of hyperthyroidism on lindane-induced hepatotoxicity in the rat

Parameters related to hepatic oxidative stress, cell injury, phagocytic activity, and liver histology were studied in control rats and in animals subjected to L-3,3',5-triiodothyronine (T3) and/or lindane administration. Hyperthyroidism elicited a calorigenic response and increased rates of hepatic O2 uptake, which were not modified by lindane treatment. T3 diminished serum lindane levels as well as those in the liver and adipose tissue, whereas lindane enhanced serum T3 levels in animals given T3. Compared with control rats, lindane significantly increased the rate of formation of thiobarbituric acid reactants (TBARS) by the liver, with no changes in either the reduced glutathione (GSH) content, the TBARS/GSH ratio as indicator of oxidative stress, or in the fractional rates of lactate dehydrogenase (LDH) and GSH efflux from perfused livers as integrity parameters. Hyperthyroidism induced GSH depletion in the liver, with a significant enhancement in the TBARS formation, the TBARS/GSH ratio, and in the fractional LDH and GSH efflux. These parameters were increased further by joint T3 and lindane administration in a magnitude exceeding the sum of the effects produced by the separate treatments. In addition, hyperthyroidism led to Kupffer cell hyperplasia and significant increases in serum glutamate oxalacetate transaminase (GOT) and in hepatic zymosan-induced chemiluminescence, while liver myeloperoxidase (MPO) activity was found unchanged, compared with controls. Rats treated with lindane presented normal liver histology, with no changes in biochemical parameters related to cell injury. The joint administration of T3 and lindane, however, elicited a marked elevation in serum GOT and glutamate pyruvate transaminase (GPT), concomitantly with extensive liver necrosis and the presence of granulomas containing lymphocytes, Kupffer cells and polymorphonuclear leukocytes (PMN). In this condition, hepatic zymosan-induced light emission and MPO activity were enhanced over control values. It is concluded that hyperthyroidism increases the susceptibility of the liver to the toxic effects of lindane, which seems to be accomplished by potentiation of the hepatic oxidative stress status. The latter effect may be conditioned by an enhanced phagocytic respiratory burst activity due to the observed Kupffer cell hyperplasia and PMN infiltration, in addition to the increased production of reactive oxygen species in parenchymal cells.

Factors associated with male workers' engagement in physical activity: white collar vs. blue collar workers

The purpose of this study was to identify factors associated with male workers' participation in different kinds of physical activity, noting differences between white collar and blue collar workers. This study examined the variables, perceived health status, self efficacy, perceived barriers, age, education, income, and job category (Pender, 1987) for their association with physical activity. Self efficacy and perceived health status were the cognitive-perceptual factors that predicted physical activity. Job category (e.g., blue collar vs. white collar) was found to be a highly significant predictor of physical activity. Comparing physical job requirements with the individual worker capacity can suggest to the occupational health nurse physical fitness programs that are most appropriate for individual workers.
